Intertissue differences in the hysteretic behaviour of carnitine palmitoyltransferase in the presence of malonyl-CoA

Biochem J. 1986 Jul 1;237(1):289-91. doi: 10.1042/bj2370289.

Abstract

In the presence of malonyl-CoA, the overt form of carnitine palmitoyltransferase (CPT1) in mitochondria from rat liver, kidney cortex, heart, skeletal muscle and brown adipose tissue shows non-linear time courses, suggesting hysteretic behaviour. The pattern of this hysteresis is similar in heart, skeletal muscle and brown adipose tissue, but the hysteretic behaviour of the enzyme in these three tissues differs markedly from that seen in liver and kidney.
